Answer:
Only sponges (phylum Porifera) have asymmetrical body plans. Some animals start life with one type of body symmetry, but develop a different type as adults; for example, sea stars are classified as bilaterally symmetrical even though their adult forms are radially symmetrical.

Starfish belongs to the phylum Echinodermata. Species of this phylum are radially symmetrical. So, starfish is not asymmetrical. Echinoderms in larval stage are bilaterally symmetrical. During transformation from larva to adult echinoderm, due to torsional effect, adult echinoderm are radially symmetrical.
